Let R f = ℤ [ A ± 1 ] be the algebra of Laurent polynomials in the variable A and let R a = ℤ [ A ± 1 , z 1 , z 2 , … ] be the algebra of Laurent polynomials in the variable A and standard polynomials in the variables z 1 , z 2 , … . For n ≥ 1 we denote by VB n the virtual braid group on n strands. We define two towers of algebras { VTL n ( R f ) } n = 1 ∞ and { ATL n ( R a ) } n = 1 ∞ in terms of diagrams. For each n ≥ 1 we determine presentations for both, VTL n ( R f ) and ATL n ( R a ) . We determine sequences of homomorphisms { ρ n f : R f [ VB n ] → VTL n ( R f ) } n = 1 ∞ and { ρ n a : R a [ VB n ] → ATL n ( R a ) } n = 1 ∞ , we determine Markov traces { T n ′ f : VTL n ( R f ) → R f } n = 1 ∞ and { T n ′ a : ATL n ( R a ) → R a } n = 1 ∞ , and we show that the invariants for virtual links obtained from these Markov traces are the f -polynomial for the first trace and the arrow polynomial for the second trace. We show that, for each n ≥ 1 , the standard Temperley–Lieb algebra TL n embeds into both, VTL n ( R f ) and ATL n ( R a ) , and that the restrictions to { TL n } n = 1 ∞ of the two Markov traces coincide.

让R F = ℤ [ 一种 ± 1 ] 是变量中的 Laurent 多项式的代数一种 然后让R 一种 = ℤ [ 一种 ± 1 , z 1 , z 2 , … ] 是变量中的 Laurent 多项式的代数一种 和变量中的标准多项式z 1 , z 2 , … . 为了n ≥ 1 我们表示VB n 虚拟编织组n 股。我们定义了两个代数塔{ VTL n ( R F ) } n = 1 ∞ 和{ ATL n ( R 一种 ) } n = 1 ∞ 在图表方面。对于每个n ≥ 1 我们确定两者的演示文稿,VTL n ( R F ) 和ATL n ( R 一种 ) . 我们确定同态序列{ ρ n F : R F [ VB n ] → VTL n ( R F ) } n = 1 ∞ 和{ ρ n 一种 : R 一种 [ VB n ] → ATL n ( R 一种 ) } n = 1 ∞ ,我们确定马尔可夫迹{ 吨 n ' F : VTL n ( R F ) → R F } n = 1 ∞ 和{ 吨 n ' 一种 : ATL n ( R 一种 ) → R 一种 } n = 1 ∞ ,我们证明了从这些马尔可夫迹中获得的虚拟链接的不变量是F -多项式用于第一道,箭头多项式用于第二道。我们证明,对于每个n ≥ 1 , 标准 Temperley-Lieb 代数TL n 嵌入两者,VTL n ( R F ) 和ATL n ( R 一种 ) ,并且限制{ TL n } n = 1 ∞ 两条马尔可夫轨迹重合。
